Fall Gear Check Reminder from HydroStat LLC! 🍂
Before you store your Scuba tanks for the winter, make sure they're ready to go when the spring season starts!
Here’s what to check for:
🔍 Hydrostatic Test Date: Cylinders need a new hydro test every 5 years. Look for the date stamped on your tank. If it’s been longer than 5 years, now’s the time to schedule the test.
Keep in mind that hydro testing can be a time-consuming process, so don’t wait until next season starts!
🔍 Visual Inspection (VIP): We can perform this inspection test on your threads to ensure there's zero defects in your threads!
🔧 Bring your tanks to HydroStat LLC for inspections and testing before storing them full for the off-season.
Proper maintenance ensures your gear is ready to dive right into the spring!
